>>951123Yup, on snow and dirt.
Easier to log tracks from, easier to get waypoints in/out of.
Topo for all of US, street maps with fuel/hotel/food/etc POI's for US/Canada/Mexico. No data plan, no cell service, etc needed. Tough as fuck too. Easier to power off sled/moto.
Phone stays in airplane mode in the pack. If there's an emergency, I'd rather have that battery power for calls instead of burning it all logging tracks.
Garmin runs on 2xAA batteries, along with my phone and flashlight, so I can swap things out if things do go south.
